The Mercedes-Benz S-Class Long (V221 facelift), specifically the AMG S 65 V12 Automatic produced from 2010 to 2013, represents the pinnacle of luxury and performance within the V221 generation. Positioned as the flagship variant of the long-wheelbase S-Class, it catered to buyers demanding the utmost in exclusivity, power, and refinement. The “Long” designation indicates an extended wheelbase, providing significantly increased rear passenger legroom, a feature particularly popular in markets like China and among chauffeur-driven clientele. This model was a key component of Mercedes-Benz’s strategy to maintain dominance in the ultra-luxury sedan segment, competing directly with the Rolls-Royce Phantom and Bentley Flying Spur.

Powertrain & Engine Architecture
The heart of the AMG S 65 is the M275.982 6.0-liter V12 engine. This engine is a marvel of engineering, featuring twin turbochargers, a multi-port fuel injection system, and four valves per cylinder. The engine’s architecture is a 60-degree V12, providing inherent smoothness and balance. The twin turbochargers, strategically positioned within the V of the engine, deliver significant boost, contributing to the engine’s prodigious 1000 Nm (737.56 lb-ft) of torque. The engine utilizes an air-to-water intercooler to manage intake temperatures. Paired with the engine is a five-speed automatic transmission (7G-Tronic), specifically tuned by AMG for rapid and smooth gear changes. While a five-speed may seem dated by modern standards, it was robustly built to handle the immense power and torque output of the V12.
Driving Characteristics
The AMG S 65 delivers a driving experience characterized by effortless power and remarkable composure. The 630 horsepower and massive torque reserves provide breathtaking acceleration – 0 to 60 mph in approximately 4.2 seconds. However, the true appeal lies in the engine’s ability to deliver seamless, surge-free power across the entire rev range. The five-speed automatic transmission, while not offering the latest gear count, is well-programmed and provides quick shifts. Compared to the S 550 with its twin-turbo V8, the S 65 offers a significantly more refined and powerful experience. The V8, while still potent, lacks the sheer gravitas and smoothness of the V12. The S 65 also differs substantially from the diesel-powered S 350 CDI, which prioritizes fuel economy over outright performance.
Equipment & Trim Levels
The AMG S 65 came standard with a comprehensive array of luxury features. Interior appointments included premium leather upholstery, wood trim, and brushed aluminum accents. Standard equipment included a panoramic sunroof, heated and ventilated front and rear seats with massage functions, a premium sound system, and a rear-seat entertainment system. The long wheelbase provided ample rear legroom, making it ideal for chauffeured transport. Optional extras included a refrigerator in the rear center console, bespoke interior customization options, and advanced driver-assistance systems. The exterior was distinguished by AMG-specific body styling, including unique front and rear bumpers, side skirts, and a rear spoiler.
Chassis & Braking
The S 65 featured an AIRMATIC suspension system, providing a comfortable ride while maintaining excellent handling characteristics. The suspension automatically adjusts damping rates based on road conditions and driving style. The car was equipped with disc brakes on all four wheels, coupled with an Anti-lock Braking System (ABS) and Electronic Stability Program (ESP) for enhanced safety. The braking system was designed to cope with the car’s substantial weight and high speeds. The S 65 also featured a speed-sensitive steering system, providing increased assistance at low speeds and reduced assistance at high speeds.
Market Reception & Comparison
The AMG S 65 was generally well-received by automotive critics, who praised its exceptional performance, luxurious interior, and refined driving experience. However, its high price tag and substantial fuel consumption were often noted. Compared to the S 550, the S 65 offered a significant step up in performance and exclusivity, but at a considerable cost. The S 65’s fuel economy, averaging around 16.4 US mpg combined, was considerably lower than that of the S 350 CDI, which could achieve over 30 mpg. Reliability was generally good, although the complexity of the V12 engine and its associated systems meant that maintenance costs could be high.
Legacy
The AMG S 65 V12 (V221) remains a highly sought-after vehicle in the used car market, particularly among collectors and enthusiasts. The M275 V12 engine, while complex, has proven to be relatively durable when properly maintained. However, potential buyers should be aware of the high cost of repairs and the need for specialized servicing. The V221 S-Class, and particularly the AMG S 65, represents a high point in Mercedes-Benz’s commitment to luxury and performance, and continues to be regarded as a benchmark in the ultra-luxury sedan segment.
